Photocoupler

Summary:

The flyback power supply converts an AC input from 90 VAC to 264 VAC to a 5 V, 1.2 A (6 W) single isolated DC output. The output voltage regulation tolerance is controlled within ±5% of the input voltage, load, and temperature changes without the need for an optocoupler.

design feature

• Elimination of optocoupler and all secondary side control circuits
• EcoSmart? – Easily meet all current and proposed international energy efficiency standards – CoC / China (CECP) / EISA / DoE / European Commission
• On/Off control provides constant efficiency at very light loads
• No-load power consumption <80 mW at 230 VAC input
• Meets the ENERGY STAR 2.0 requirements for efficiency in the load mode (requires 70%, up to 77%)
• Ultra-low leakage current: <5 μA at 265 VAC input (no Y capacitor required)
• Overheat protection – Strict tolerance range (±5%) plus hysteresis recovery ensures PCB temperature is safe under all conditions
• Automatic restart output short circuit and open loop protection
• Easily meet EN550022 and CISPR-22 Class B EMI standards
• Green package: halogen-free and RoHS compliant
